GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

Google unveiled Gemini 4 Argon, which is strong at cyber defense and will be offered to trusted defenders without cyber guardrails, and cybersecurity stocks fell; OpenAI executives said they are also building security products around Astra.

Anthropic and OpenAI both expanded their London offices this year, and the London team reportedly played a major role in training Astra.

Gemini 4 Argon was reportedly tested before release; without it Astra wins 10 of 19 tests, and the author gives model picks by use case.

The poster says Gemini 4 Argon matches Astra on the Intelligence Index at about 40% lower cost per task with discounted pricing, and wants to see how it handles real projects.

George Hotz said he gave the first assignment of a CMU course to GPT-6 Astra and it got an F, raising the question of whether students are prepared for the course.

A developer observed that messages passed between Astra/Sol subagents have almost no spaces or punctuation and contain only keywords, speculating this comes from pure RL without RLHF.

Starting from a single historical scan, Astra transcribed about 1,300 handwritten cipher units, reconstructed 155 symbols and ran an annealing solver to recover a March 1809 military briefing to General Marmont.

An OpenAI-related account shared an in-person event in Kazakhstan where founders, builders and students built projects with GPT-6 Astra.

The author split overnight work across five Astra cloud agents, approved once at 1:32 a.m., and woke to a completed task list and a claimed $8,400 gain.

The author describes a multi-model workflow where Astra high orchestrates, GPT6.1 Sol high does engineering, and Luna high works as worker and tester.

The article argues DevDay's real story is not a model release but GPT-6.1 Sol plus the Agents API, computer use and subagents, which can build agents that persist, act and check their own work.

A post claims GPT-6 Astra solved an encrypted message from one of Napoleon's generals that had gone unbroken for 217 years.
